in this study, we aimed to investigate reproductive performance in estrus-induced zandi ewes treated with equine chorionic gonadotrophin (ecg) injection in combination with prostaglandin f2α (pgf2α)and gonadotrophin releasing hormone (gnrh) during non-breeding season. the estrous cycle was synchronized using controlled internal drug release (cidr) for 12 days. the ewes were randomly assigned to...

This research investigated the effect of stress mid-pregnancy shorn Zandi ewes on live birth weight and body sizes twin lambs. A total 96 ewes, confirmed pregnant with twins, were randomly allocated day 80 pregnancy into 4 groups, each group containing 6 replicates (each replicate sheep). The experimental groups included: 1. Control, 2. Crutched, 3. Sham-Shorn, 4. Shorn. Blood cortisol concentr...

the aim of this study was to evaluate the effect of estradiol (e2), oxytocin (ot), relaxin (relaximol) injection and prostaglandin e1 (misoprostol) suppository on the cervix dilation, time of cervical dilation persistency and pregnancy rate of zandi ewes using artificial insemination. eighty 3-4 years old and 55±2.5 kg weight ewes were used for this study. in experiment 1, the ewes were assigne...

the aim of this study was to determine the effects of ecg, pgf2α and gnrh hormone on improvement of reproduction performance of cidr synchronized zandi ewes in breeding season. 500 ewes with age of 2.5-4 years and same nutritional condition were selected for this study and received cidr for 12 days. then these ewes were assigned to five equal groups. first group received no hormone (control gro...

the aim followed in the present study was to evaluate the effect of estradiol (e2) injection and injection (either intramuscular (i.m) or intravenous (i.v)) of various doses of oxytocin (ot) on cervix dilation and on conception rate in zandi ewes during late breeding season. sixty three ewes were randomly selected. in experiment 1, the ewes received 100 µl e2 and 12h later were divided and assi...

Leptin (LEP), the expression product of the obese gene produced primarily in the adipose tissue, is related to feed intake, growth and lipid metabolism. The aim of this study was to study the possible association between polymorphism of the LEP gene with growth and carcass traits among three Iranian sheep breeds of the Shal, Zandi and Zel varieties. A total of 180 purebred animals of the Shal, ...

In this study, we aimed to investigate reproductive performance in estrus-induced Zandi ewes treated with equine chorionic gonadotrophin (eCG) injection in combination with prostaglandin F2α (PGF2α)and gonadotrophin releasing hormone (GnRH) during non-breeding season. The estrous cycle was synchronized using controlled internal drug release (CIDR) for 12 days. The ewes were randomly assigned to...
